The force source presented here was developed to measure psychophysical data of human force perception. For this purpose, it delivers sinusoidal forces with amplitudes of up to 10 N at frequencies of up to 1000 Hz in one DoF. Deflection exceeds 0.2 mm at all frequencies. Forces are generated using an electrodynamic actuator. To ensure high accuracy, a force control scheme is used. Intended measurements will include the Just Noticeable Difference (JND) and curves of equal perception.
